KEYSTACK and someone else's MessageBox?

[vefatica]

I want to automate pressing "Y" when my editor prompts "OK to create ..." with a message box. Here's my attempt so far, TPAD.BTM.

::TPAD.BTM
setlocal
echo on
set noexist=0

do i=1 to %#
    if not exist %[%i] set noexist=%@eval[%noexist + 1]
enddo

d:\TextPad7\TextPad.exe %$

iff %noexist GT 0 then
    do i=1 to %noexist
        keystack /w18 "Y"
    enddo
endiff

If I issue tpad.btm xx1.txt xx2.txt (both files non-existent), I see

set noexist=0
do i=1 to %#
if not exist %[%i] set noexist=%@eval[%noexist + 1]
if not exist %[%i] set noexist=%@eval[%noexist + 1]
d:\TextPad7\TextPad.exe xx1.txt xx2.txt

The first message box appears and that's it! The BTM doesn't continue until I have (manually) dismissed both message boxes and the keystrokes wind up in one of the documents. What's going on there? Is there anything I can do about it?

It's easy enough to work around ... either build and execute the KEYSTACK command before starting TEXTPAD, or forget KEYSTACK and simply create the files (TOUCH /C /Q) before starting TEXTPAD.

But I'm still wondering how the execution of the BTM was suspended in my original approach.
